You know the broken drive shaft bolt thread? I can one up that...

[603NytroXTX]

So....long story short I did a 1.75 track swap with extros etc to update my 09 XTX to 13' spec. Looks like I didn't put enough Loctite on my new drive shaft bolt because I just found this beauty. I read about people not even putting that bolt in and I guess I should have listened. When I was doing the swap I had the broken bolt and did 5k miles with no issues. The bolt that drilled its way through the cover was just sitting in the fairing below. I have no idea how long I rode with it like that. Time for a new housing $154.00 later

Been down that road. I put a rubber plug in it and put silicone around it

So you never ran into any issues without the bolt? How many miles would you guess. If I remember correctly the only thing that bolt does is hold the collar/sleeve on the shaft and keep it from touch the housing/cover

I put the bolt back in on my nytro and Red loctite with loctite primer

Wouldnt the oil pour out of the chaincase with the hole in the side? MS

Not with the rubber plug and silicone on it.

Great mid-season fix! Seeing how I still have 6 months till I can ride I think I'm going to get the new housing/cover but good to know that it worked for you. Thanks for the responses

Just get it welded.

been there, took apart and inspected everything, found the c-clip that is suppose to stop the bolt from coming out if it does loosen. From what I see the bolt holds the spring,bottom gear in place during chaincase assembly. If it falls out during operation you do loose oil but nothing else happened, maybe I just got lucky. Drilled threads to hold a plastic pipe plug. No I have an inspection hole. haha

That bolt is what keeps the driveshaft where it's supposed to be. If for example the set screws were not tight on the left side driveshaft bearing, then the drive shaft could move to the left.

Thank you, I wondered about this and I did remove my speedometer sendor/pickup gear and inspect that bearing. I grease it every year and it hadn’t moved during this episode. the set screws were tight And shaft didn’t move. But something had to have forced the screw to back out. I keep checking through my “new inspection hole” 2,000 miles now and hasn’t loosened yet. Sled does have 21,000 miles. 2012 venture GT

If I remember correctly yours has the longer drive shaft and end adaptor to match.
I would just conclude that the last time this was apart, the bolt may have been put back in without loctite.
Factory spec does call for this bolt to have loctite.
In addition, use brake clean and compressed air to clean the threads, bolt and in end of shaft as oil residues negate the locking effect of loctite.

Mine did the exact same thing. Wound up JB Welding the hole and putting orange Loctite on the bolt along with a new C-clip. Stronger than blue but not as strong as red.
